Note: Telnet and Web management may be used to modify settings of the
firewall or disable it. The user may also change local IP addresses and other
settings, making it difficult or impossible to access the GlobeSurfer 3G from
the local network. Therefore, remote access to Telnet or HTTP services
should
be blocked
and should only be permitted when absolutely necessary.
Encrypted remote administration is done using a secure SSL connection, that
requires an SSL certificate. When accessing GlobeSurfer 3G for the first time us-
ing encrypted remote administration, you will be prompted by your browser
with a warning regarding certificate authentication. This is due to the fact that
GlobeSurfer 3G’s SSL certificate is self generated. When encountering this mes-
sage under these circumstances, ignore it and continue. The self generated cer-
tificate is safe, and provides you with a secure SSL connection.
It is also possible to assign a user-defined certificate to GlobeSurfer 3G. To learn
about certificates, see Section
6.9
